Writing Inks The common writing fluids depend mostly upon galls. Logwood or aniline for coloring. There are literally thousands of formulas. A few of the most reliable have been gathered together here: 1. – Aleppo galls (well Bruised), 4 ounces; clean soft water, 1 quart; macerate in a clean corked bottle for 10 days or a fortnight or longer, with frequent agitation; then add of gum Arabic (dissolved in a wineglassful of water), 1½ ounces; lump sugar, ½ ounce. Mix well, and afterwards further add of sulphate of iron (green copperas crushed small), 1½ ounces. Agitate occasionally for 2 or 3 days, when the ink may be decanted for use, but is better if the whole is left to digest together for 2 or 3 weeks. When time is an object, the whole of the ingredients may at once be put into a bottle, and the latter agitated daily until the ink is made; and boiling water instead of cold water may be employed. Product, 1 quart of excellent ink, writing pale at first, but soon turning intensely black. 2. – Aleppo galls (bruised), 12 pounds; soft water, 6 gallons. Boil in copper vessel for 1 hour, adding more water to make up for the portion lost by evaporation; strain, and again boil the galls with water, 4 gallons, for ½ hour; strain off the liquor, and boil a third time with water, 2½ gallons, and strain. Mix the several liquors, and while still hot add of green copperas (coarsely powdered), 4½ pounds; gum Arabic (bruised small), 4 pounds, agitate until dissolved, and after defecation strain through a hair sieve, and keep in a bunged cask for use. Product, 12 gallons. |
